The rotating device has a central pipeline 10 (Pig. 1) for the inlet of the pouring agent, to which pipeline a plate 11 is firmly attached and this in turn is medium Bolt 12 attached to the side 13 of the body 14 of a sheath 15, which extends into a cylindrical bearing housing 16. Inside the bearing housing 16 is through a bearing 17 through it, a shaft 18 rotatably mounted, which ends in the machine part 19, which latter houses the paddle wheels, so this machine part is located between the plate 11 and the shell 15.

The plate 11 is sometimes also called the "stator" here and the machine part 19 is sometimes called the "rotor" here, However, the subject matter of the invention also includes devices in which the plate 11 rotates and the machine part 19 is stationary is, as well as devices in which plate 11 and machine part 19 ″ both perform different rotary movements ©

The paddle wheels 20 (Pig. 2) are in longitudinal slots 21 in Body 19 "of the rotor and housed in the disk 19", which is firmly attached with its inside to the body 19 ', j

^{R 81/5} 609828/0268

and the blades are angled in the same intervals \

around the axis of the rotor. The paddle wheels 20 rotate:

in relation to the machine part that carries them, namely:

around their own axes 22, which are perpendicular to the axis of:

¹ each 18 stand and the axes 22 are at the connection point;

of the body 19 ^f with the disk 19 "housed. ί

Each paddle wheel 20 consists of two wheels 23 and 24 (Pig. 3), which adjoin one another with their sides. The wheel 23 has
a part 25 of each blade and the wheel 24 has one part
26 of each blade, the parts 25 and 26 of the blades, which are side by side, form a blade 27. The longitudinal sides 28 and 29 of the blades are at a variable distance due to the action of the pedals 30 and 31, which on the
Parts 25 "and 26, respectively, of the blades act to keep them spaced apart. The superimposed zones 32 and 33 of the parts
25 and 26 of the blades are less thick than sides 28 and 29;

In another embodiment of the invention, each vane may have more than two movable parts. ;

In another embodiment of the invention (Pig. 5 and 6) i each paddle wheel consists of two paddle wheels 101 and 102 \ with blades 25, 26, which in Pig. 3 and 4 shown j

are similar. The bodies 103 and 104 of the paddle wheels 101 and! 102 are mounted with their sides against each other so that the \ possibility of relative rotation exists between them. A pe- j of 105 is at the one extreme end 106 of the body 103 and | attached to the other extreme end 107 of the body 104, the peder tending to rotate both paddle wheels with respect to each other in the direction which gives each paddle its maximum width. The peder 105 is stored in annular cavities 108 and 109 in the bodies 103 and 104, wherein
these cavities face each other.

The blades 27 of variable width operate in a sliding manner by means of
its frontal sides 36 "(Pig. 7) coincide with the bottom 37 of the spiral passages 38 in the plate 11, the latter

609828/0268

facing disk 19 ". In addition to bottom 37, the spiral passage is defined by an inner sidewall 40, which is formed by rib 41 in the form of a spiral protruding from the body of the plate 11 (Fig. 8), whose an extreme end 42 (Fig. 8) is in the vicinity of a central opening 43 of the plate 11 is located and the other extreme end 44 is in the vicinity of an annular space 45 is located in the body 14. A spiral passage 38 .. becomes so bordered by a first spiral rib 41 -j and one second spiral rib 41p, which in the present example is angularly offset by 90 ° with respect to the first. The back 46.J and 46p of these passages are curved so that they are with a conjugate rotating surface 47 formed on the disk 19 "sealingly cooperates.

The device according to the invention has a device 48 with spiral walls, which is formed by a central ring 51 (FIG. 9) and a circumferential ring 52, between which spiral walls 53 are attached. In the present embodiment, four such walls 53 ^, 53 ₂ »53 * and 53 λ are present and in fact of such a shape that the spiral walls conjugate with the shape of the passages 41. The walls are in relation to one another by 90 around the axis 54 "? which the rings 51 and 52 is common, angularly offset. In addition, partially cylindrical units 55 »56, from which the outer ends 57 of the spiral walls 53 depend, are firmly connected to the circumferential ring 52.

Therefore, for a given angular position of the device 48, the spiral walls 53 are by means of their outer sides 58 united with the outer side walls 49 of the passages 38. For such a condition shown in Fig. 10, there are Cross-sections of the passages for the circulation of the fluid are at a maximum and, consequently, the displacement of the rotating device maximum when the rotor 19 with the paddle wheels 20 turns.

During the relative rotation of the plate 11 and the machine part 19 with the paddle wheels, there is a superplastic __ R 81/5

! between the central opening 45 and the space 45, which has its origin in the movement of the blades 2 * 7 of the wheels 20 in the circulation lines, which take up the chau. These circulation lines are enclosed - in addition to the inner side walls 40 of the passage 38 - by the bottom 37 of the convex surface 47 and by the inside 59 of the spiral wall 53 which is accommodated in this passage. This wall 53 is connected to the outer side wall 4? ie ε passage united. The longitudinal sides 28 and 29 of a blade circulating in a single line are, by the action of the springs 30 and 31 or 105? on the one hand against the inner side wall 40 of the passage, and on the other hand against the inside 59 of the spiral wall 53. Such a ^r jtellur is ir. ~ Fl 7, the reference numeral 1 -tlt shown schematically. The rotation works in this case with a condition of maximum displacement.

j By relative rotation of the device 48 with walls and j j rings in relation to the plate 11 of the stator in the direction i j of the arrow f in FIG. 10, the spiral walls j 53 move away from the outer flanks 49 of the passages 38 and ] For example, a position as shown schematically in FIG. 7 by reference number 2.

would, which is not equipped with a spiral wall.

The position indicated by reference number 3 for the spiral wall 53 in Pig. 7 is shown corresponds schematically to the position for which the displacement of the device is a minimum is. One such condition of the device is in Pig. 11 shown.

The units 55 and 56 prevent direct communication between the inlet and the outlet of the fluid circulating in the device. The inner sides of the units 55 and 56 have a shape which conjugates with the outer side of the ribs 41. In addition, the units 55 and 56 can be made in one piece. At the end of the walls 55 'which is closest to the center, the outside of the walls cooperate with the inside of the end 41 of the passage. The change in the displacement can be achieved by operating the device 48 with the walls by hand.

The invention also provides an embodiment in which changing the displacement is achieved by using the Driving fluid in the space between the outer side wall of the passage and the wall which is in this passage is located, introduces. This insertion is controlled in relation to the working conditions of the device.

Such an arrangement of movable spiral walls can in Rotary devices are used, which constructed as hydraulic pumps, motors, compressors, turbines or gas engines are. It allows all such devices to be built with variable displacement.

In the case of a gas turbine, which is shown schematically in Pig. 12-12 have wheels 603 which are adapted to rotate about axes 604 are mounted, blades 605 »which on the one hand in the spiral circulation lines 606 of the stator 607 of the compressor 601 circulate. The compressor has variable displacement in view of the fact that the spiral passages of the Stator 607 accommodate the spiral walls 53, which are a first device for controlling the displacement _

belong, and that the paddle wheels 603 blades are more variable Have width, so that the width of the circulation lines is adjustable.

The blades 605 also circulate in the spiral circulation lines 608 of the stator 609 of the actual machine 602. These circulation lines have a cross-section which changes when a second device 53 with spiral walls is displaced, which, however, is maximal for the condition Displacement of the machine has its walls in contact with the inner side walls of the passages and not with the outer side walls, as is the pail in the compressor 601. The body 610 of the rotor has on one side a first inwardly curved surface 611 of rotation about the axis of rotation 612 of the rotor, which cooperates with the upper surfaces 613 of the ribs 614 and the adjacent passages of the stator 607 with the backs 614 ^{f of} the opiral: Walls 53 borders.

The body 610 of the rotor, on the other hand, facing the stator 609 of the machine, has a second inwardly curved surface 615 of rotation around axis 612 which cooperates with the upper surfaces 613 of the ribs 617 and the passages 608 of the stator 609 with the back 618 of the spiral walls 53 ^{r of} the second device, whereby the sealing of the circulation lines is ensured.

The air entering the compressor through a screen protected central inlet 621 reaches the central one Opening of the stator 607 of the compressor and is made by the circulation of the blades 605 of the wheels 603 in the spiral Passages of the stator 607 compressed and under pressure through the circumferential conduit 624 into a combustion chamber 625 emptied. This combustion chamber has an inner compartment 626 to which the fuel is fed through a supply device 627 is forwarded. The mixture of the air under pressure with the fuel, which may be generated by an ignition device 628 or ignited by the rise in temperature due to the rise in pressure, generates high-temperature combustion gases.

The latter are mixed with part of the compressed air, which circulates along a circumferential circuit 629 of the chamber. The whole is accomplished through input line 631 through the circumference of the stator 609 of the machine 602, where the internal energy of the hot gases is used to direct through Effect on the blades 605 of the wheels within the passages 608 of the stator 609 to drive the rotor 610, v / elcher houses these wheels. The gases leave the passages 608 at the central part of the stator 609 and are via an output line 632 deducted. The work is collected on shaft 633 of rotor 610, with the shaft in bearings 634 and is held.

The angular displacement of the first control device with spiral Walls allow the displacement of the compressor to be changed. The angular displacement of the second controller with spiral walls allows the displacement of the machine itself to be changed.

The invention therefore also creates a simultaneous change in the same quantity of displacement of the compressor and the Moving the actual machine.
